Deafness with Labyrinthine Aplasia, Microtia, and Microdontia, also known as hearing loss with labyrinthine aplasia, microtia, and microdontia, is related to deafness, congenital, with inner ear agenesis, microtia, and microdontia and pyridoxamine 5-prime-phosphate oxidase deficiency. An important gene associated with Deafness with Labyrinthine Aplasia, Microtia, and Microdontia is FGF3 (Fibroblast Growth Factor 3). Affiliated tissues include eye and skin, and related phenotypes are hearing impairment and widely spaced teeth
